G4648–σκοπέω–skopeō

Therefore see whether the light that is in you isn't darkness.

σκόπει skopei “do take heed”

Now I beg you, brothers, look out for those who are causing the divisions and occasions of stumbling, contrary to the doctrine which you learned, and turn away from them.

σκοπεῖν skopein “to watch out for”

while we don't look at the things which are seen, but at the things which are not seen. For the things which are seen are temporal, but the things which are not seen are eternal.

σκοπούντων skopountōn “are looking at”

Brothers, even if a man is caught in some fault, you who are spiritual must restore such a one in a spirit of gentleness; looking to yourself so that you also aren't tempted.

σκοπῶν skopōn “considering”

each of you not just looking to his own things, but each of you also to the things of others.

σκοποῦντες skopountes “considering”

Brothers, be imitators together of me, and note those who walk this way, even as you have us for an example.

σκοπεῖτε skopeite “do observe”
